A Fourier analysis is a technique that is able to determine both the amplitude spectrum and the phase <span>spectrum of any signal</span>. This analysis is based on the finding that all sound waves can be derived by adding sinusoids together (so long as the sinusoids are of the appropriate frequencies, amplitudes, and phases).
Based on the key I think it’s option 1
Answer:
The correct answer will be option-D.
Explanation:
Biologists have identified eight characteristic feature of a living organism which distinguishes the living organism from non-living organism.
The features are that organisms should contain: cells, heredity material, metabolism, reproduction, sensitivity, homeostasis, growth and development.
In the given question, when the scientist hypothesized that structure is living organism then it should show all the options provided as all of these features are shared by the living organism.
Thus, option-D is the correct answer.
